# Audio Underwater Effect Simulate the sound of being underwater > Canonical page: https://elysiatools.com/en/tools/audio-underwater-effect - **Category:** Media - **Keywords:** audio, underwater, submarine, diving, muffled, aquatic, bubbles, filter ## Overview Creates the muffled, filtered sound of hearing audio underwater using low-pass filtering, bubbling sounds, and pressure effects. Perfect for diving scenes, submarine audio, and aquatic environments. ## Inputs - **Audio File** (file): Select an audio file - **Water Environment** (select): Type of underwater environment. Each has different acoustic characteristics. - **Muffling Effect (0-1.0)** (range): How muffled and filtered the sound appears. Higher = more underwater, less clarity. - **Bubble Intensity (0-1.0)** (range): Amount of bubbling sounds mixed in. Higher = more active aquatic environment. - **Pressure Effect (0-1.0)** (range): Simulates water pressure on audio. Creates subtle pitch and modulation changes. - **Depth (1-100 meters)** (number): Simulated water depth. Deeper = more muffled and low-pass filtered sound. - **Wet/Dry Mix (0-1.0)** (range): Balance between dry (original) and wet (underwater) signal. - **Output Format** (select) ## When to use - When creating audio for diving or underwater scenes in films, videos, or documentaries. - When simulating submarine or deep-sea audio for video games, simulations, or virtual reality experiences. - When adding aquatic ambiance to podcasts, music tracks, or sound effects for themed content. ## How it works - Upload an audio file in a supported format such as MP3, WAV, or OGG. - Select a water environment type (e.g., deep ocean, shallow water) to define the acoustic characteristics. - Adjust parameters like muffling effect, bubble intensity, and pressure effect to customize the underwater sound. - The tool applies low-pass filtering, mixes in bubble sounds, and outputs the modified audio in your chosen format. ## Use cases - Enhancing film or video audio for underwater scenes to improve immersion and realism. - Creating immersive sound effects for video games set in aquatic or deep-sea environments. - Producing themed audio content for podcasts, music, or sound design with an underwater vibe. ## Frequently asked questions ### What audio file formats can I upload? You can upload audio files in common formats including MP3, AAC, M4A, OGG, Opus, FLAC, and WAV. ### How do I control the level of muffling? Use the muffling effect slider from 0 to 1.0; higher values make the sound more underwater and less clear. ### What does the depth parameter affect? Depth simulates water depth in meters, influencing the low-pass filter; deeper settings result in a more muffled sound. ### Can I add bubble sounds to the audio? Yes, adjust the bubble intensity from 0 to 1.0 to mix in bubbling sounds for a more active aquatic environment. ### Is there a limit on audio file size? Yes, the audio file must be under 200 MB; check the tool's file limit for details. ## Related tools - [Invert Channel Phase](https://elysiatools.com/en/tools/audio-invert-phase): Invert the phase of one channel (for vocal removal effect) - [Audio Radio Effect](https://elysiatools.com/en/tools/audio-radio-effect): Simulate the sound of an old AM radio - [Audio Reverse Reverb](https://elysiatools.com/en/tools/audio-reverse-reverb): Apply a reverb effect that builds up before the sound - [Audio Room Simulator](https://elysiatools.com/en/tools/audio-room-simulator): Simulate the acoustics of different room sizes - [Audio Non-Silence Detector](https://elysiatools.com/en/tools/audio-non-silence-detector): Detect and list the parts of the audio that contain sound - [Audio Sibilance Map](https://elysiatools.com/en/tools/audio-sibilance-map): Map harsh S, T, and SH regions so de-essing can target the right moments instead of dulling the whole voice. - [Audio Band-Reject Filter](https://elysiatools.com/en/tools/audio-band-reject-filter): Remove a specific band of frequencies - [Audio Bitcrusher](https://elysiatools.com/en/tools/audio-bitcrusher): Reduce the sample rate and bit depth for a lo-fi effect ## Samples - [Copyright-Free FLAC Audio Samples](https://elysiatools.com/en/samples/flac-samples): Lossless FLAC audio samples for testing and development, mirrored from MP3 set with nature sounds and meditation music - [Copyright-Free MP3 Audio Samples](https://elysiatools.com/en/samples/mp3-samples): Collection of royalty-free audio samples for testing and development purposes including nature sounds, meditation music, and ambient audio - [Copyright-Free WAV Audio Samples](https://elysiatools.com/en/samples/wav-samples): Uncompressed PCM WAV audio samples for testing and development, mirrored from MP3 set with nature sounds and meditation music - [Copyright-Free Raw PCM Audio Samples](https://elysiatools.com/en/samples/pcm-samples): Raw PCM s16le audio samples featuring nature ambience and relaxing music for waveform, playback, and conversion workflows ## Related content - [Audio Reverb, Modulation, and Sound Design Effects Tools](https://elysiatools.com/en/hubs/audio-sound-design-effects): Choose, preview, compare, and verify reverb, delay, modulation, and character effects for music, video, podcast, and game sound design.
